Maryland, a rise of one inch per decade has been cited as a cause of wetlands 

 loss . 



These isolated observations may become the general rule in the future. 

 Although world-wide sea- level rose only four to six inches in the past 

 century, the National Academy of Sciences and the Environmental Protection 

 Agency have estimated that the expected "greenhouse" warming is likely to 

 cause a one to five ft rise in the next century. (Introduction).

 City, Maryland," United States Environmental Protection Agency, Washington,

This study examines the potential implications of sea- level rise for 

 efforts to control erosion of the beach at Ocean City, Maryland, a typical 

 Atlantic Coast resort. Because current trends in sea- level and other factors 

 are already causing significant erosion at Ocean City and other ocean beach 

 resorts, strategies for addressing coastal erosion constitute a class of near- 

 term decisions that may depend on sea- level rise. Because land and improve- 

 ments are often worth well over one million dollars per acre in these areas, 

 and erosion increases the likelihood of storm damage and federal disaster 

 payments, the success of erosion control measures has great economic impor- 

 tance to the nation. The authors hope that this report will promote a rea- 

 soned consideration of the long-term consequences of sea-level rise, and 

 thereby enhance the eventual success of erosion control strategies at Ocean 

 City and other coastal communities. 



In this report, three independent teams of coastal process scientists 

 estimate the erosion that will take place at Ocean City for three scenarios of 

 future sea-level rise: (1) current trends of 1 ft per century along the 

 Atlantic coast; (2) the National Academy of Sciences estimate of a 2-1/3 ft 

 global rise in the next century with an 11 inch rise by 2025; and (3) the EPA 

 mid-high scenario of a global rise of 4-1/2 ft in the next century and 

 15 inches by 2025. The quantity of sand necessary to maintain the current 

 shoreline is also estimated for each of the scenarios. Using these estimates 

 and previous studies by the Corps of Engineers and others, the potential costs 

 of erosion control are also examined. (Summary) .

 Hemisphere Sea-Level Pressure Data Set: Trends, Errors and Discontinuities," 

 Monthly Weather Review . Vol 108, pp 855-872. 



A detailed examination of the Northern Hemisphere monthly mean sea- level 

 grid-point pressures shows a disappointingly large number of problems. The 

 data set extends from 1899-1977 but has originated from eight different 

 sources and discontinuities have been identified with every change in source. 

 We have documented corrections for many of these and have also catalogued 3263 

 serious errors. These have been corrected or set to missing. Most of the 

 errors are over Asia and are predominant before 1922 or during World War II.
